Abstract
Mechanical shear connectors, such as headed studs and Perfobond ribs, are generally used in steel-concrete composite structures. Such shear connectors may affect negatively on construction as well as increase cost and weight. To improve constructability and to simplify the connecting structures, a composite slab system using a cementitious adhesive has been developed in previous works. The present study aims to examine shear capacity of the composite structure by performing a push-out test. The test results indicate that the developed composite system has almost equal strength to the conventional composite structure using Perfobond. The observation confirms the shear performance can be enhanced by the adhesive and notched stiffeners (half-hole).
